FIELD

This disclosure relates to devices and systems for light control. More specifically, the disclosed embodiments relate to light control devices and light control systems to control a light strip in response to detection of an object or a motion of an object in a vicinity of an entranceway of a room.

INTRODUCTION

Automatic light control is desired and already available to some extent. However, there are some problems with current automatic light control systems using a motion detector. For example, a light control system can turn off while a user is still present in a room but does not move enough. In other cases, the light stays on for a certain time period (or even indefinitely) after the user closes the door to a room, which results in wasted energy. A light control system with an automatic door jamb switch may solve some of the above issues. However, the automatic door jamb switch is typically installed by a qualified electrician when the home is built. Therefore, there exists a need for a light control system enabling desired automatic control and allowing easy installation and retrofitting in an existing space.

SUMMARY

The present disclosure provides systems, apparatuses, and methods relating to control the light strip.

According to one aspect, a light control system for a LED light strip in a room is provided. The LED light strip is positioned at least partially along a perimeter of an entranceway of the room. The light control system comprises a sensor module disposed on a first vertical portion of the entranceway and configured to detect a tapping on the first vertical portion by a user and a light control device. The light control device includes a housing, a battery pack removably installed in the housing, a proximity sensor configured to detect a position of a door in a vicinity of the entranceway, and a light controller disposed in the housing and in communication with the sensor module and the proximity sensor. The light control device is disposed adjacent a free side of the door when the door is closed; and is configured to control light from the light strip in response to a detected position of the door by the proximity sensor, and to control the light strip in response to a tapping pattern when the door is not detected within a preset distance from the entranceway by the proximity sensor.

According to another aspect, a light control system for a light strip in a room is provided. The light strip is positioned at least partially along a perimeter of an entranceway of the room.

Examples, Components, and Alternatives

The following sections describe selected aspects of illustrative light control devices as well as related systems and/or methods. The examples in these sections are intended for illustration and should not be interpreted as limiting the scope of the present disclosure. Each section may include one or more distinct embodiments or examples, and/or contextual or related information, function, and/or structure.

A. Illustrative Light Control Systems and Light Control Devices

FIG. 1 shows a light strip control system 20 in accordance with aspects of the present disclosure, illustrating light strip control system 20 or a light control system 20 and an environment in which light strip control system 20 may be implemented. Light strip control system 20 comprises a light control device 22 and a light strip 24. Light strip control system 20 may be installed on a frame 26 enclosing an entranceway 28 of a room 30. Room 30 may be any inner space having an entranceway. For example, room 30 may be a closet, a storage room, a cabinet, or essentially any space where it is desirable to provide and/or control the lighting based on motions at the entranceway, such as motions of a door disposed in the entranceway. In some embodiments, light strip 24 may be a LED light strip. Light strip 24 may be disposed at least partially along frame 26 of entranceway 28. Frame 26 may include a header 32, a first vertical portion 34 and a second vertical portion 36. In the present application, header 32, first vertical portion 34 and second vertical portion 36 are used interchangeably with a header, a first jamb, a second jamb of entranceway 28, and their corresponding adjacent header trim, first vertical side trim, second vertical side trims of adjacent trims. In other words, light strip 24 may be disposed at least partially along or on the header, the first vertical side jamb and second vertical side jamb of entranceway 28 in one embodiment or disposed at least partially along or on the header trim, the first vertical side trim and the second vertical side trim in another embodiment.

Light control device 22 is connected to light strip 24 to control on and off of the light from light strip 24. Light control device 22 may include a light controller 38 and an activity sensor or a first activity sensor 40. Light controller 38 may include a processor and a memory. Activity sensor 40 detects an object in a vicinity of entranceway 28, a motion in the vicinity of entranceway 28, or a motion relative to entranceway 28 and sends signals to light controller 38. Activity sensor 40 may be a passive infrared (PIR) sensor, a time of flight (ToF) sensor, a magnetic field detector or any other form of proximity sensor. In some embodiments, light controller 38 controls on and off of light strip 24 based a detected object in the vicinity of entranceway 28 or based on a position of the object in a vicinity of entranceway 28. In some embodiments, light controller 38 controls on and off of light strip 24 based a motion pattern of an object detected by activity sensor 40.

Continuing FIG. 1, in the illustrated embodiment, room 30 may be a closet and entranceway 28 may be an opening of the closet. A door 42 is pivotally connected to second vertical portion 36 of frame 26 and configured to open toward an interior of room 30. Light strip 24 is used to provide light only, function as a primary light source, or a supplement light source for the closet. Light strip 24 has a connected end 44 and a distal end 46 opposite connected end 44. In the illustrated embodiment, light strip 24 extends substantially along an entire length of frame 26 from connected end 44 to distal end 46. It should be appreciated any light strip 24 may have any appropriated length to provide desired illumination. For example, a length of light strip 24 along frame 26 may be greater than 51% a perimeter of frame 26. In another example, the length of light strip 24 may be approximately 75% of the perimeter of frame 26. In yet another example, the length of light strip 24 may be approximately 85% of the perimeter of the frame 26. Light strip 24 may comprise multiple segments which are connected to form a desired length. Alternatively, connected end 44 may be disposed on a middle position on first vertical portion 34 closer to header 32 than a floor 48 or closer to floor 48 than header 32.

In the illustrative embodiment, light control device 22 is disposed inside room 30 adjacent to first vertical portion 34 of frame 26, connected to connected end 44 of light strip 24 and positioned on floor 48 of room 30. Alternatively, light control device 22 may be disposed on the middle position of first vertical portion 34 and connected to connected end 44 on the middle position directly or may be disposed on floor 48 and connected to connected end 44 via wire.

As light control device 22 is disposed on first vertical portion 34 adjacent to a free side 50 of door 42, activity sensor 40 can detect opening of door 42 when free side 50 of door 42 moves away from first vertical portion 34 and detect closing of door 42 when free side 50 moves toward first vertical portion 34. In some embodiments, activity sensor 40 may be a time of flight (ToF) sensor. The ToF sensor measures the time it takes an infrared (IR) beam to reflect off a nearby object, and it can determine a distance to the object from that information. When door 42 opens, activity sensor 40 can determine a distance of door 42 to activity sensor 40 and/or a motion pattern of door 42. In this way, different light modes are possible by programming light controller 38. Light controller 38 may be configured to turn on or turn off light strip 24 based on a distance of door 42 to a reference object such as activity sensor 40 or a housing of light control device 22. For example, light controller 38 may control light strip 24 to turn on once activity sensor 40 detects that door 42 moves away from first vertical portion 34. In another example, light controller 38 may control light strip 24 to turn on when door 42 moves away a predetermined distance from light control device 22. That is, light strip 24 is not turned on immediately after door 42 is opened. Instead, light strip 24 is turned on after door 42 has opened the predetermined distance. In yet another example, light strip 24 is turned off after activity sensor 40 detects that door 42 moves near or touches first vertical portion 34. In yet another example, light strip 24 is turned off after activity sensor 40 detects a motion pattern of door 42. The motion pattern may be a speed of door movement greater than a threshold, a sequence of opening, closing and opening, or any combination of opening and closing.

In some embodiments, activity sensor 40 may be a passive infrared (PIR) sensor. The PIR sensor measures infrared (IR) light radiating from an object in its field of view. Humans and inanimate objects emit a certain amount of IR radiation. The PR sensor may consist of at least one pyroelectric sensor and a Fresnel lens. The curved lens concentrates infrared radiation toward the pyroelectric sensor. That is, the sensor view is a beam pattern. The PR sensor receives concentrated amount of infrared energy under certain zones. When an object, such as a person, passes in front of the background, the temperature at that point in the sensor's field of view will rise from room temperature to body temperature, and then back again. The sensor converts the resulting change in the incoming infrared radiation into a change in the output voltage and send out the signal. A field of view of the PIR sensor may be less than 180° and may be as wide as 360°. In some embodiments, activity sensor 40 may be a proximity sensor. In one example, proximity sensor 40 is a magnetic field sensor such as a Hall Effect sensor and includes a sensing body disposed in housing 60 and a magnet 41 attached to free side 50 of door 42 and substantially aligned with the magnetic field sensor at a height direction H. In one example, magnet 41 faces light control device 22 when door 42 is closed. When door 42 moves away from light control device 22, the magnetic field detected by activity sensor 40 changes. The magnetic sensor detects the change of magnetic field to determine a distance of door 42 to the activity sensor 40 or detect a motion of door 42. Similarly, the magnetic field detected by activity sensor 40 changes when door 42 moves toward light control device 22. In some embodiments, light controller is configured to turn on light strip 24 when free side 50 of door 42 is detected to be spaced apart from first vertical portion 34 at a first predetermined distance (i.e., a door opening event) and turn off light strip 24 when the door is detected to be spaced apart from first vertical portion 34 at a second predetermined distance (i.e., a door closing event). The first predetermined distance is greater than the second predetermined distance. In one example, the second predetermined distance may be about zero.

It should be appreciated that various types of proximity sensors to detect a presence of a nearby object may be used as activity sensor 40. For example, the proximity sensor may be a short-range infrared (IR) sensor. In other example, the proximity sensor may be a capacitive sensor, a capacitive displacement sensor, a Doppler effect sensor, an inductive sensor, an optical sensor (e.g., photoelectric, photocell (reflective), a laser rangefinder), a passive sensor (e.g., charge-coupled devices), a passive infrared sensor, a passive thermal infrared sensor, a radar, a reflection of ionizing radiation sensor, a sonar, an ultrasonic sensor, or a fiber optics sensor.

It should be appreciated that activity senor 40 may be connected to a hinge side of door 42. The hinge side is opposite to free side 50 and connected to frame 26.

In some embodiments, light control system 20 may include a plurality of light strip clip 52 attached to frame 26 or on a wall adjacent to frame 26 to secure light strip 24. Light strip clips 52 may be attached on frame 26 via adhesive at selected positions. The light strip clip will be described in detail in FIGS. 8-12.

In some embodiments, light controller 38 and activity sensor 40 of light control device 22 are at least partially contained in a housing 60. In some embodiments, light control system 20 may further include a transceiver 64 disposed in housing 60 of light control device 22 to enable communication with an electronic device 65 such as smart phone. For example, a user may select a light control mode via a user interface on electronic device 65. Further, light control device 22 may send an alert to electronic device 65 alerting a low battery level of a battery pack 68.

As shown in FIG. 1, light control device 22 may include an electrical plug 66 to be coupled to a power outlet. Light control device 22 may further include an adaptor (not shown) to provide direct current (DC) power appropriate for light control device 22 and light strip 24. Alternatively or additionally, light control device 22 may include a battery pack 68 to provide power.

In some embodiments, light control system 20 may further comprise a sensor module 70 to detect a position/motion of a user's hand relative to entranceway 28 or to detect the user's hand signals and electrically communicate with light controller 38. Sensor module 70 may be disposed on at a position approximately around a middle point of first vertical portion 34 or a position to detect hand signals/hand gestures of a user. In some embodiments, sensor module 70 may be an accelerometer installed flush against first vertical portion 34 or a door jamb. In one embodiment, a spring 72 may be used to bias accelerometer 70 against the door jamb. When a user knocks or taps the door jamb gently, the vibration will be detected by accelerometer 70. Light controller 38 may be configured to recognize and determine different motion patterns of knocking/tapping by a hand of the user and activate corresponding light modes. Light controller 38 may be configured to control the light strip 24 only in response to the tapping patterns detected by accelerometer 70 when door 42 is detected by activity sensor 40 to be remained at an opening position for a preset time period or no door is present in entranceway 28. In other words, when a door is not detected at a preset distance from light control device 22 or no door installed in entranceway 28, controlling light strip 24 in response to detected tapping patterns from accelerometer 70 overrides the controlling light strip 24 in response to the signal from activity sensor 40. The tapping pattern may be a number of taps on the first vertical portion 34 or door jamb at a predetermined time period. For example, light controller 38 is configured to turn on light strip 24 when the tapping pattern is tapping once on first vertical portion 34 by a user and turn off light strip 24 when the tapping pattern is tapping twice on first vertical portion 34 by the user. In another example, light controller 38 is configured to turn on light strip 24 at a lower brightness when the tapping pattern is tapping three times on first vertical portion 34 by the user. Various tapping patterns may be possible to be recognized by light control 38 and control light strip 24 accordingly. It should be appreciated that accelerometer may be installed on the vertical portion or the door jamb at any appropriate position. For example, the accelerometer may be installed at a position between a middle point of the vertical portion or the door jamb as long as the tapping/knocking by the user can be detected by the accelerometer. In some embodiments, sensor module 70 may be a short-range infrared (IR) sensor that detects a position/a motion of a user's hand signals in a vicinity of vertical portion or a door jamb. The motion pattern may be the user's hand signals such as extending into entranceway 28 and then retracting back. For example, light strip 24 is turned on when the user waves a hand once across entranceway 28 and light trip 24 is turned off when the user waves a hand twice across entranceway 28. Various hand signals may be possible to create patterns recognizable by light controller 38.

In some embodiments, sensor module 70 may include a capacitive-touch sensor that detects a touch pattern of a user's hand on sensor module 70.

Although sensor module 70 is illustrated to be positioned separately from activity sensor 40, it should be appreciated that various configurations are possible. For example, a sensor module and an activity sensor may at least partially be enclosed in a sensor housing. In one embodiment where the sensor module is an accelerometer and the activity sensor is a proximity sensor or a short-range IR sensor, both accelerometer and the proximity sensor or the short-range IR sensor may be enclosed in the sensor housing. The sensor housing may be installed a halfway on the door jamb or at a position for easy detection of hand signals (e.g., tapping patterns). In some embodiments, an ambient light sensor may also be included in the sensor housing and all sensors are included in the sensor housing. Alternatively, the sensor housing and the housing for the light controller may be combined. That is, the control related components such as various sensors and light controller are integrated in one housing.

It should be appreciated that the sensor module may be any appropriate sensor module that that can detect the user's hand signals relative to the entranceway or an interaction of the user's hand to the vertical portion of the entranceway. For example, the sensor module may be a button to create a motion pattern by a user and the motion pattern is recognizable by the light controller.

Light control system 20 may further comprise a connecting device 90 to connect light control device 22 or light control system 20 with a home automation system.

FIG. 2 shows a light strip control system or a light control system 120, illustrating another of light control system 120 and an environment in which light control system 120 is implemented. Light control system 120 is used for an entranceway 128 closed by a first door 142 a and a second door 142 b. Entranceway 128 may be an opening of a closet. First door 142 a and second door 142 b may be sliding doors moveable along a rail (not shown) to open and close entranceway 128. Light control system 120 is similar to light control system 20. For the sake of brevity, in this example, the elements and features similar to those previously shown and described will not be described in much further detail. In other words, differences between the present embodiment and the embodiment of FIG. 1 will be mainly described. Light strip control system 120 comprises a light control device 122 and a light strip 124. Light strip control system 120 may be installed on a frame 126 enclosing an entranceway 128 of a room 130. In some embodiments, light strip 124 may be a LED light strip. Light strip 124 may be disposed at least partially along frame 126 of entranceway 128.

Light control device 122 is connected to a first end of light strip 124 to control on and off of light strip 124. Light control device 122 may include a light controller 138 and an activity sensor or a first activity sensor 140 a. First activity sensor 140 a detects an object in a vicinity of entranceway 128 or a vicinity of first vertical portion 134 and sends signals to light controller 138. First activity sensor 140 a may be a passive infrared sensor, a time of flight (ToF) sensor, a proximity sensor or a magnetic field detector. In some embodiments, light controller 138 controls on and off of light strip 124 based on a motion pattern of first door 142 a or second door 142 b detected by first activity sensor 140 a or based on a presence of first door 142 a or second door 142 b in a vicinity of entranceway 128.

Continuing FIG. 2, in the illustrated embodiment, room 130 may be a closet. A length of light strip 124 along frame 126 may be greater than 51% a perimeter of frame 126 of entranceway 128. Light strip 124 has a connected end 144 and a distal end 146 opposite connected end 144. At a first closed position, first door 142 a is adjacent to a first vertical portion 134 and second door 142 b is adjacent to second vertical portion 136. In one embodiment, first door 142 a is slidable along a width of entranceway 128 until one edge is adjacent to second vertical portion 136 such that first door 142 reaches a second closed position. At the second closed position, first door 142 a is adjacent to second vertical portion 136 and second door 142 b is adjacent to first vertical portion 134. Light control device 122 is disposed inside room 130 adjacent to first vertical portion 134 of frame 126 and connected to connected end 144 of light strip 124. First activity sensor 140 a detects a position or a presence of first door 142 a or second door 142 b in a vicinity of light control device 122 or adjacent to first vertical portion 134. That is, first activity sensor 140 a detects opening and closing of first door 142 a or second door 142 b relative to first vertical portion 134.

Light control system 120 may further comprise a second activity sensor 140 b and is held in a second housing 180. Second housing 180 is positioned adjacent to second vertical portion 136. Second activity sensor 140 b is disposed in second housing 180 at a position to detect a position or a motion of second door 142 b or first door 142 a in a vicinity of second vertical portion 136. Signals from second activity sensor 140 b may be transmitted to light controller 138 by data line along light strip or wirelessly. In other words, second activity sensor 140 b is communicated with light controller 138 via the data line of light strip 124.

For instance, the light control device of this embodiment may be configured to turn on the light strip when the door (such as an edge portion of the door) is detected to be spaced apart from a housing of the light control device (such as the housing of first activity sensor 140 a or the housing of second activity sensor 140 b) by a first predetermined perpendicular distance and turn off the light strip when the door is detected to be spaced apart from the housing by a second predetermined perpendicular distance, and the first predetermined perpendicular distance is greater than the second predetermined perpendicular distance. In this manner, the light control device can be configured to turn on the light strip when a sliding door is opened by some desired amount, and to turn off the light strip when the sliding door is closed to a predetermined (and perhaps user selectable) extent.

In some embodiments, second activity sensor 140 b is electrically connected to light strip 124 so that it is powered by voltage from distal end 146 of light strip 124.

FIG. 3 shows a light strip control system or a light control system 220, illustrating another light strip control system 220 and an environment in which light control system 220 is implemented. Light control system 220 is used for an entranceway 228 without a door. Light control system 220 is similar to light control system 20. For the sake of brevity, in this example, the elements and features similar to those previously shown and described will not be described in much further detail. In other words, differences between the present embodiment and the embodiment of FIG. 1 will be mainly described. Light strip control system 220 comprises a light control device 222 and a light strip 224. Light strip control system 220 may be installed on a frame 226 that runs around a perimeter of an entranceway 228. In some embodiments, light strip 224 may be a LED light strip. Light strip 224 may be disposed at least partially along frame 226 of entranceway 328.

Continuing FIG. 3, in the illustrated embodiment, room 230 may be a closet. A length of light strip 224 along frame 226 may be greater than 51% a perimeter of frame 226 of entranceway 228. Light strip 224 has a connected end 244 and a distal end 246 opposite connected end 244. Light control device 222 is disposed inside room 230 adjacent to a first vertical portion 234 of frame 226 and connected to connected end 244 of light strip 224.

Light control device 222 is configured to control on and off of the light strip 224. Light control device 222 may include a light controller 238 and an activity sensor 240. Activity sensor 240 detects an object or a motion pattern in a vicinity of first vertical portion 234 of entranceway 228 and send signals to light controller 238. The object may be a person. Activity sensor 240 may send a signal to trigger the light on when the person walks across the entranceway or when a hand of the person passes through a plane containing the entranceway. In some embodiments, activity sensor 240 may be a PIR sensor.

FIGS. 1-3 illustrate exemplary environments in which the light control systems and light control devices of the present disclosure may be implemented. It should be appreciated that the light control systems and light control devices of the present disclosure can be implemented in other environments or in various enclosures. For example, the room may have various types of doors, such as a door pivotally connected to an opening via hinges, a bifold door, or a sliding door. In other examples, the room may be a closet, a storage room, a drawer, a cabinet, or essentially any space where it is desirable to provide and/or control the light.

FIG. 4 is a schematic block diagram of a light strip control system 420 according to one aspect of the present disclosure. Light strip control system or light control system 420 comprises a light control device 422 to control light or light from a light strip 424 based on signals from a first activity sensor 440 a and/or a second activity sensor 440 b. First activity sensor 440 a and second activity sensor 440 b are configured to detect a position and/or a motion pattern of an object in a vicinity of an entranceway. First activity sensor 440 a and second activity sensor 440 b may be a passive infrared sensor, a time of flight (ToF) sensor, a proximity sensor, a magnetic field detector or any appropriate sensors that detects a position of an object or a motion of the object.

Light controller 438 controls on and off of light strip 424 based on signals from first activity sensor 440 a and is configured to have a plurality of light modes. In some embodiments, light control modes may be activated automatically based on a presence of an object or a motion pattern of an object in a vicinity of an entranceway. For example, light is controlled to be turned on when an object (e.g., a door) is detected to move a predetermined distance away from the entranceway and to be turned off when the object is detected to move toward the entranceway. In one example, a sensing distance to trigger the operation of the light strip may correlate a position of first activity sensor on a housing of light control device 422. In one embodiment, the sensing distance is fixed. However, the position of first activity sensor 440 a on a housing of light control device 422 may be adjusted and thus the position of the object at which the light is controlled to be turned on or off can be adjusted although the sensing distance is fixed. For example, first activity sensor 440 a may be disposed on a selector mechanism on the housing of light control device 422. A user can adjust the position of first activity sensor 440 a via the selector mechanism such that, for instance, light is turned on when a door has opened to a desired distance.

Light controller 438 may be configured to recognize and determine different motion patterns and activate corresponding light modes. The motion patterns may be based on the interaction of an object relative to the entranceway. The object may be a door of the entranceway or a person. In some embodiments, a first motion pattern may be a movement of the door away from the door or opening of the door, which corresponding to a mode of light being on. A second motion pattern may be a movement of the door toward the door or closing of the door, which corresponding to a mode of light being off. In another example, a motion pattern of opening, closing and reopening of the door may correspond to a “no disturbance” mode. At the “no-disturbance” mode, the light strip 424 is off even the door is open. Similarly, in a setting in which there is no door at an entranceway, a motion pattern of a user's hand gesture of extending into, retracting and reextending into the entranceway can be recognized and interpreted as a command to activate the “no-disturbance” mode. A “night light” mode may further be implemented via another motion pattern. For example, a motion pattern of opening, closing, reopening, closing and reopening of a door may correspond the “night light” mode in which light stays on at a lower brightness (approximately 20% of brightness for example) to provide night light for the room or an adjacent room. Motion patterns may include various combinations of the movements of the object relative to the entranceway, various interactions with the entranceway and/or speeds of the movement. Light controller 438 may be configured recognize the motion patterns and activate the light modes accordingly. It should be appreciated that the light modes are not limited to the modes described above and various light mode may be possible. For example, the mode may include a specific time, a door distance, a light intensity, a light color, a period for light being turning and a motion speed of an object, and any combinations of above parameters. When the light controller is connected to an electronic device such as a smart phone, a user may input a desired mode via a user interface and the light controller will execute the instructions and control the light accordingly.

In some embodiments, light control device 422 may include a socket adapter configured to plug into a light fixture in the room to draw power. Socket adapter is described in detail in FIG. 14. In this scenario, a light switch 492 in the room can be set up in the “on” position all the time. Light controller 438 may be programmed to recognize the motion patterns of light switch 492 and activate corresponding light modes. For example, a motion pattern of light switch 492 in a sequence of “off” and then “on” may activate a “no-disturbance” mode. In another example, a motion pattern of “off”, “on”, and then “off” may activate a “night light” mode.

In some embodiments, light control system 420 may further comprise an accelerometer 470 electrically communicated with light controller 438. The interaction with the entranceway is knocking or tapping on the entranceway. For, example, accelerometer 470 may be installed to flush up against a door jamb. When a user knocks or taps the door jamb or an area adjacent to accelerometer 470 gently, the vibration will be detected by accelerometer 470. Light controller 438 may be configured to recognize different motion patterns of knocking/tapping and activate corresponding light modes or control the light strip accordingly.

In some embodiments, light control device 422 may further comprise an ambient light sensor 480 to detect ambient light and determine light intensity of light strip 424 appropriate for the surrounding environment.

In some embodiments, light controller 438 may be configured to connect with an electronic device 466 such that the light control modes may be set up by a user via a user interface on electronic device 466. Light controller 438 may be communicated with electronic device 466 wirelessly. For example, a transceiver 464 may be included in a housing of light control device 422. In one embodiment, electronic device 466 may be a smart phone.

Via the light control application in the electronic device, a user can customize the light control mode. For instance, the light actuation may be set up to depend on the ambient light conditions via a user interface on the electronic device. In one example, a light control system may be configured to control the light strip installed under a kitchen cabinet, by turning on whenever the overhead light is turned on and turning off when an ambient light intensity exceeds a threshold. The ambient light intensity may be detected by an ambient light sensor. The user may also set up different modes for different hours in the day. For example, the light strip can be controlled to turn on at certain hours during the day regardless whether the overhead light is on.

In some embodiments, light control system 420 may further comprises a connecting device 490 for connecting light control system 420 to a home automation system.

In some embodiments, light control device 422 may include a battery 462 to provide the power needed by light control system 420.

In some applications, an entranceway may include two doors. First activity sensor 440 a is configured to detect a position and/or a motion of a first door and a second activity sensor 440 b is configured to detect a position and/or a motion of a second door. Light control device 422 is disposed on a first vertical portion adjacent to the entranceway. Second activity sensor 440 b is disposed in a second housing which is disposed on a second vertical portion opposing the first vertical portion. Second activity sensor 440 b may be connected to one end of light strip 424 to acquire a voltage needed for its function. Alternatively, second activity sensor 440 n may be connected to light control device via wire. Further, second activity sensor 440 b may be connected to light controller 438 wirelessly or via a data line in light strip 424.

FIG. 5 is a perspective view of an illustrative light control device 522 in accordance with aspects of the present disclosure. FIG. 6 is a cross-sectional view of a selector mechanism of the light control device in FIG. 5. Referring to FIG. 5, light control device 522 comprises a housing 510 and a selector mechanism 512. In the illustrated embodiment, selector mechanism 512 is a rotatable wheel disposed on a top section 514 of housing 510. More generally, a selector mechanism according to the present teachings can be any movable or rotatable mechanism such as a switch, lever, dial, or the like, which is capable of being moved either continuously or discretely to a plurality of positions. Top section 514 is recessed from an upper surface 515 to create a receiving space to hold rotatable wheel 512. An activity sensor 540 is mounted on rotatable wheel 512 and moveable with rotatable wheel 512 or moveable relative to the housing. A light controller 538 is schematically shown in FIG. 5. Light controller 538 is disposed in housing 510 and configured to control a light strip based on a position, a motion and/or a motion pattern of an object in a vicinity of an entranceway. Housing 510 includes a slot 511 to receive a connected end of the light strip.

Activity sensor 540 is moveable with rotatable wheel 512 and can be secured at a plurality of selected positions upon a user selection. One selected position corresponds to one position of the object at which light strip is on when an object is detected. Light control device 522 may be calibrated to have multiple positions of the object at which light is on and/or off. A user can select a position of the object at which light is turned on by the selector mechanism 512 (e.g. rotatable wheel). In some embodiments, an indicator 513 may be shown on selector mechanism 512 to indicate a door opening position when the light is turned on. For example, indicator 513 may include scales 1, 2, and 3 corresponding degrees of a door opening position relative to a vertical portion of the door (e.g., door opened 15°, 25° and 45° relative to a plane P containing the entranceway). In the illustrated example, the user can move rotatable wheel 512 to adjust or calibrate the position of the object at which light is on and/or off.

Alternatively or additionally, light control device 522 may further comprise an ambient light sensor 570 to detect ambient light and determine appropriate light intensity of the light strip for the surrounding environment. In the illustrated embodiment, ambient light sensor 570 is disposed on rotatable wheel 512 at the same side as activity sensor 540. It should be appreciated that ambient light sensor 570 may be disposed at any appropriate places in housing 510.

In some embodiments, light control device 522 may further comprise an auxiliary sensor 518 for use in a “no door” setting. The “no door” setting refers to an environment in which there is no door at the entranceway or a condition where a door is left open. Auxiliary sensor 518 may be a PIR sensor. Auxiliary sensor 518 may be positioned on a middle portion of rotatable wheel 512. Auxiliary sensor 518 includes Fresnel lens 530 which concentrates infrared radiation to a beam pattern in a cone distribution. The cone distribution would create a zone outside the entranceway. FIG. 5 shows an imaginary plane P separates a room from an outside space. Light control device 522 is mounted in the room on one side of an imaginary plane P. As the field of view of auxiliary sensor 518 is straight up in a cone distribution, a zone of the cone distribution outside the room would detect a motion or an object outside the room and adjacent the entranceway. The light from the light strip thus activated by detection of outside object is undesirable. To address the issue, rotatable wheel 512 is configured to include a partial cover 532 to conceal a portion of Fresnel lens 530 of auxiliary sensor 518. For example, partial cover 532 can be rotated toward in a direction away from the room. As a result, the zone of the cone distribution outside the room is removed from the field of view to create a PIR blind spot such that presence of the object outside the entranceway is undetectable by the PIR sensor. In this way, the object or the motion of the object outside the room would not be detected and light is thus not activated accordingly.

Referring FIG. 5 and FIG. 6, in some embodiments, a top surface 534 of rotatable wheel 512 may be inclined toward auxiliary sensor 518 to form a reverse hollow frustum with an opening 536. Fresnel lens 530 is configured to protrude from opening 536 and an upper surface 544 of Fresnel lens 530 is positioned to be lowered than an upper edge 546 of rotatable wheel 512. Partial cover 532 extends from an arcuate edge 548 of rotatable wheel 512 toward auxiliary sensor 518 and partially covers rotatable wheel 512. In the illustrative embodiment, Partial cover 532 further partially covers auxiliary sensor 518.

In some embodiments, activity sensor 540 is positioned on a side of housing 510 corresponding partial cover 532. That is, partial cover 532 and activity sensor 540 move together. When activity sensor 540 is aimed at a door, partial cover 532 is at a position to block the field of view of auxiliary sensor 518 that is outside the entranceway.

Selector mechanism 512 is illustrated to be a rotatable wheel 512 in FIG. 5 and FIG. 6. It should be appreciated that selector mechanism can take various forms and can be placed in a plurality of positions on or in housing 510. For example, selector mechanism may include a slider moveable on a rail on the housing. Activity sensor 540 may be disposed on the slider. The position of detected object at which the light is activated can be adjusted or calibrated by moving the slider and securing slider at a preset position.

Light control device 522 is versatile and can be used in various configurations of entranceways. For example, light control device 522 can be use in a room with a door. Opening or closing of the door turns the light on or off. At a condition when the door is left open, auxiliary sensor 518 plays a role to control the light strip automatically. For example, walking into the closet activates the light while a motion outside the closet would not trigger the light due to the blind spot created by partial cover 532.

A light control device may be configured for use only for a no-door application. For example, the light control device for the no-door application may be similar to light control device 522 except without activity sensor 540. In this embodiment, auxiliary sensor 518 is a primary sensor for the light control device.

In some embodiments, light control device 522 may further comprise a battery pack 562 with rechargeable battery 563. Battery pack 562 may include one or multiple rechargeable batteries and an AC adapter. Housing 510 is configured to have a space to contain battery 563 and the AC adapter for connecting battery 563 with a power source from an electrical outlet. When light control device 522 is powered by being plugged into the power source, battery 563 is charged. Battery pack 562 may be used as a sole power source or as a supplement power source for light control device 522. Battery pack 562 is configured to be removable and can be ejected from housing 510 by pressing an ejection button 516. Inclusion of the battery pack has various advantages. For example, the battery can be charged by connecting the light control device with a power outlet and the housing of the light control device is used as a casing for connecting the battery with the power outlet. The charged battery allows the light control device to be used in an enclosure without a nearby power outlet. In another example, the light control device is used in an enclosure enabling a connection with a power, the battery can be placed in the light control device to be in full capacity constantly. The charged battery can be removed out for the use with other devices (e.g., a light control device disposed in different enclosures and devices using the same type of batteries).

In one embodiment, housing 510 may have a height H, a length L and a width W of approximately 5.7 inches, approximately 2.5 inches and approximately 1.33 inches, respectively. Light control device 522 may be mounted on a floor of a room or on a vertical portion of jamb or vertical trim adjacent to the entranceway.

In some embodiments, light control device 520 may further comprise a stand 550 to hold housing 510. Referring to FIG. 7, Stand 550 includes a base 552 and a back support 554 extending from base 552 at in a height direction H1 of housing 510 and tabs 556 extending at the height direction H1. Back support 554 and a side surface 558 a or 558 b of housing 510 form a channel 560 to receive wires of the LED light strip. Housing 510 is configured to be slidable in and out from stand 550 with either side surface 558 a or side surface 558 b facing back support 554.

In some embodiments, a light control system may comprise a plurality of adjustable LED strip clips 600 to attach a light strip along an entranceway. Referring to FIGS. 8-11, an example light strip clip 600 is illustrated. As shown in FIG. 8, clip 600 includes a cradle piece 602 and a sickle piece 604 assembled on cradle piece 602. Referring FIGS. 8-9, sickle piece 604 includes an upper plate 606 having a flat surface 608, at least one arm 612, and a spine 614 and two side plates 610 forming an angle to upper plate 606. Arm 612 extends from flat surface 608 away from cradle piece 602 and is configured to hold a light strip. Arm 612 may have an L-shape. In the illustrated embodiment, clip 600 includes two arms 612 arranging a long a length direction L1 at one side of sickle piece 604. It should be appreciated that various configurations of arms are possible. For example, clip 600 may include a first arm and a second arm arranged at one side of sickle piece 604 and a third arm arranged at an opposite side of sickle piece 604 and positioned between the first arm and the second arm.

Continuing FIG. 9 and with further reference to FIG. 10, spine 614 of sickle piece 604 extends along a lengthwise direction L1 and is configured to be snapped into a plurality grooves 618 in cradle piece 602. A cross section of spine 614 may be a trapezoid and a distal side of trapezoid is greater than a proximal side such that spine is secured in grooves 618. Spine 614 may be made from resilient material and can be snapped in and pull out from grooves 618.

Sickle piece 604 may include two side plates 610. In the illustrative embodiment, side plates 610 extends from flat surface 608 toward a base 616 of cradle piece 602 and is substantially perpendicular to flat surface 608. Each of side plate 610 extends downward from upper plate 606 and spine 614 extends between two side plates 610 Sickle piece 604 may further include at least one support 636 between two side plates 610. Support 636 may be a segment of a circle and configured to rest on an arcuate upper surface 634 of cradle piece 602.

Referring to FIG. 10, a base 616 of cradle piece 602 includes a flat bottom surface 630. Cradle piece 602 further includes a cradle bed 632 having arcuate upper surface 634. A plurality of grooves 618 are formed on arcuate upper surface 634. In the illustrated embodiment, cradle piece 602 includes five grooves 618 a, 618 b, 618 c, 618 d and 618 e. Cradle bed 632 has an arc shape as well. In the illustrated embodiment, side plate 610 of sickle piece 604 is a segment of a circle matching the arc shape of cradle bed 632.

Spine 614 of sickle piece 604 is connectable to the cradle piece via spine 614 at a plurality of positions including a normal position, a first tilted position and a second titled position. The plurality of grooves 618 include a first groove 618 a corresponding to a lowest point of cradle bed 632, a second groove 618 b spaced away from first groove 618 a and a third groove 619 c spaced away and adjacent to second groove 618 b. Sickle piece 604 or clip 600 is at a normal position when spine 614 is positioned in first groove 618 a. At the normal position, flat surface 608 of sickle piece 604 is substantially parallel to a bottom surface 630 of cradle piece 602 as shown in FIG. 8 and the assembled light strip is oriented with a light beam in a direction substantially perpendicular to bottom surface 630 of cradle piece 602.

FIG. 11 illustrates clip 600 at a tilted position and one side plate of sickle piece 604 is removed from FIG. 11 to view underlying components. When spine 614 is positioned in third groove 618 c, clip 600 is at a tilted position at which flat surface 608 of sickle piece 604 forms an angle α with flat bottom surface 630 of cradle piece 602 as shown in FIG. 11. Similarly, when spine 614 is positioned in a second groove 618 b, clip 600 is at another tilted position at which flat surface 608 of sickle piece 604 forms another angle with flat bottom surface 630 of cradle piece 602. When spine 614 is positioned in a fourth groove 618 d or a fifth groove 618 e, clip 600 is at different tilted positions and the sickle piece 604 is tilted at a different direction.

When the light strip is installed on an entranceway, at the tilted position shown in FIG. 11, the light strip on the clip is oriented at an angle and thus the light beam from light strip is directed toward the entranceway. By positioning spine 614 in different grooves 618, the light beam from the light strip can be adjusted to have different angles relative to a mounting surface. It should be appreciated that various number of grooves such as three grooves or more than five grooves are possible.

A light strip clip may take various form such that an angle between a flat surface of the sickle piece and a flat surface of the cradle piece is adjustable. For example, sickle piece 604 may have one side plate 610. Spine 614 can be inserted into one of grooves 618 until side plate 610 touches cradle piece 602. Clip 600 may be made from plastic or any other suitable material.

FIG. 12 illustrates a light strip 24 and a light strip clip 600 at an assembled state. In some embodiments, the flat bottom surface 630 of clip 600 may include adhesive. In the illustrated embodiment, clip 600 is attached to a wall 31 and adjacent to a trim 33 of an entranceway. Light strip 24 is disposed on upper plate 606 of clip 600. A plurality of clips 600 may be disposed along a length of light strip 24 to secure light strip 24 to wall 31.
